The Biggest Loser: In part one of this week's two-part challenge, contestants divide the amount of weight they've lost so far among their opponents, with many ganging up on the player they feel is the strongest competitor. For part two of the challenge, the players head to the racetrack where they'll meet NASCAR driver Clint Bowyer. Then each contestant will pull a two-ton car - plus the weight added on from part one of the challenge -- for almost a quarter of a mile! Also, the competition goes to singles this week and contestants are given their original colored shirts to wear for the rest of the competition. And later, one contestant breaks Biggest Loser records at a weigh in that finds several players hitting big milestones.
